Having fished Spider a few times myself, walleyes and crappies are probably two of the more difficult species on Spider. It's gin clear making walleyes best pursued in darker conditions starting deeper and working shallower into the evening. Though I have never caught one myself there so take that with a grain of salt, but they do exist. Crappies, I haven't caught one there either, but have never pursued them, so can't give much for tips. We have had lots of success for largemouth, muskies, and bluegills. If you're ok eating bass, and I think they're tasty myself, you shouldn't have a problem finding some of them to take home. Weed lines and cranks or jigs would suffice, many places you can sight fish with a wacky worm rig quite successfully.
